Hi there, I recently bough my first drum set and I'd like to start to learn properly. For the past 15 years I learned a lot by lap clapping, air drumming and sneaking behind set when drummer was having a cigarette, so I'm quite ahead with independence and playing different rhythms in relation to technique itself. I noticed I can play with my right hand significantly harder, faster and more consistently than with my left hand. One big difference I can see is that when playing on snare, my left hand does that circular motion when striking / bouncing while right one bounces pretty much straight up. Surprisingly I find it very difficult to strike like that even once with my left hand, twice in a row is a miracle. This happens when blasting from behind my ear as well as barely kissing the drum from just an inch away. The first thing I did after kit purchase was to sign up for a lesson, just 1 off to have someone check my initial technique and give me some tips. Surprisingly, the man was having that circular motion in his both hands when playing fast, and he said there's nothing wrong with the way I hold sticks or hit. Internet is full of educational material but I haven't found a single mention about this issue. Obviously, it matters only on snare drum and floor tom eventually but still, and so my question is how important is to strike perfectly straight down? Is that something I should work on and eliminate before I move on to more advanced stuff (double, triple strikes, paradiddles etc), or will it just stop to play a role with my general skills going up?
